Question 22 • EA Academy Civics 9

Which describes a value for density?

Answer

A

a value for volume, such as m3, divided by a value for mass, such as kg

B

a value for mass, such as kg, divided by a value for volume, such as m3

C

a value for distance, such as m, divided by a value for time, such as s

D

a value for time, such as s, divided by a value for distance, such as m

Explanation

Density is mass divided by volume: density = mass ÷ volume. Its units can be kilograms per cubic metre (kg/m³), so the correct description is a value for mass divided by a value for volume. Choice A reverses the relationship; C and D describe distance and time instead.
